Answer:
n = 25
Explanation:
The smallest perfect square larger than 144 = 12² is 169 = 13². As it happens, the difference of these squares is 25, a number divisible by 5.
So n=25 will make all of the expressions have values that are natural numbers.
_____
n = 0 would make all of them integers, but 0/5 = 0 is not a natural number.
